Population justification: Within the species's known range there are perhaps c.500 mature individuals, equivalent to c.750 individuals in total.
Trend justification: There is some evidence of declines in the area of occupancy, quality of known habitat, number of locations and possibly the number of mature individuals (Garnett and Crowley 2000). Overall, the population is estimated to be declining, although the likely rate of decline has not been estimated.
